RAKE CLEANER ATTACHMENT William D. Havens and William A. Cryne, Schenectady, N. Y.

Application June 13, 1935, Serial No. 26,396

4 Claims. (01. 55-146) Our invention relates to a cleaner attachment I8 from members I I and tilting unloader I2 back for rakes.

An object of our invention is to provide an improved cleaner attachment for rakes which may be readily applied to the rake. A further object of our invention is to provide a rake cleaner attachment of simple construction consisting of a minimum number of parts which may be readily assembled together and will be of low cost of manufacture. What we consider to be novel and our invention will be better understood by reference to the following specification when considered in connection with the accompanying drawing in which Fig. 1 is a perspective View of. a rake with the cleaner attachment in operative position on the rake; Fig. 2 is a similar perspective View of a rake and the cleaner attachment with the cleaner in the inoperative position, and Fig. 3 is a perspective view on an enlarged scale, showing in detail a portion of the cleaner attachment. Referring to the drawing, Ill indicates a rake handle on the end of which is provided the usual rake teeth H. To remove any matter adhering to the teeth in the operation or use of the rake an unloader or cleaner bar I2 is provided. Unloader I2 is provided with openings l3 slightly larger than the shank of teeth I I and corresponding in numberto the number of teeth on the rake. Unloader I2 is formed of a U shaped channel member for rigidity to prevent it from twisting and bending and thus binding on the teeth. To move the unloader I2 to the operative position and to prevent it from falling away from the rake two combined foot and stop members M are provided. Members I4 are formed from channels with a depending V-shaped foot I5and L shaped stop It integrally connected together. Members It are secured to unloader I2 by cotter pins I1. To move the unloader I2 from the operative to the inoperative position and thus remove any foreign matter collected on teeth II, a spring I8 is provided with a loop I9 adapted to loosely fit on handle it and two arms 20. Arms 20 have hooked ends which fit in openings in stops I6 'of members It and serve to connect spring"; to 'unloader I2. The cleaner attachment is assembled to the rake by first placing the unloader I2 in position on the teeth I I with members I4 secured to it by cotter pins H. The spring I8 is next placed in position by passing loop I 9 over handle Ill and inserting the ends of arms 20 in the openings in members M. The whole cleaner assembly is thus secured in position on the rake. The cleaner is removed simply by disconnecting spring to permit stop I 6 to pass the teeth II. The spring I8 is then slipped ofi handle Ill. The securing of the spring I8 to the handle II] merely by the provision of an integral loop I 9 which loosely fits the handle greatly facilitates assembly of the cleaner on the rake and similarly makes it possible to quickly remove the cleaner when it isnt needed. When the arms 20 of spring I8 are connected to members I4 the loop I9 is held in posi-, 10 tion on handle I0 by the spring tension produced by the arms 20. In the operation of the cleaner as the rake is moved back and forward with the teeth II in engagement with the ground, the unloader I2is moved to the operative position in- 15 dicated in Fig. .1 by the engagement of the two feet I5 of members I4 with the ground. When it is desired to remove any foreign matter from teeth I I the rake is merely lifted from the ground and the tension of spring I8 moves unloader I2 to the position indicated in Fig. 2. Further down- 20 ward movement of unloader I2 is prevented by stops I (i of members I I engaging the crossmember of teeth II. Obviously, any foreign matter is removed from teeth II in the passage of unloader I2 from the operative position of Fig. 1 tothe inoperative position of Fig. 2.

From the foregoing it may be seen that a rake cleaner attachment is provided consisting of three parts of simple construction which may be readily locatedin position and secured to the rake and similarly removed from the rake when it is desired to use the rake without such attachment.

What we claim as new and-desire to secure by Letters Patent of the United States, is: 35

l. A cleaner attachment for rake teeth comprising an unloader having openings for the teeth, a combined foot and stop member secured to said unloader, and an actuating spring having a loop adapted to pass freely over the rake handle and an arm integral with the loop connected to said member.

2. A cleaner attachment for rake teeth comprising an unload-er having openings for the teeth, combined foot and stop members secured to said 45 unloader, and a spring'having a loop loosely fitting the handle of the rake and integral arms connected to said combined foot and stop members.

3. A cleaner attachment for rakes comprising 50 an unloader having openings for the rake teeth,

a foot secured to the unloader and adapted to move it to the operative position, a spring having a loop fitting the rake handle and integral 7 arms connected to the unloader and adapted to 55 move it to the inoperative position, and a stop secured to the unloader and serving to limit the movement of the unloader to the inoperative position.

4. A cleaner attachment for rakes comprising an unloader having openings for the rake teeth, a foot secured to the unloader and adapted to hold it in one position, a stop secured to the unloader andadapted to limit the movement of the unloader to a. second position, and a spring having a loop fitting the rake handle and integral arms connected to the unloader and adapted to move the unloader from said one position to said second. position whereby any foreign matter collected on the rake teeth is removed.
